Wrench.



FRANKLIN P. BATES, OF INDIANAPOLIS, INDIANA.

WRENCH.

SPECIFICATION forming part of Letters Patent No. 684,037, dated October8, 1901.

Application filed October 9, 1900. Serial No. 32,488. (No model.)

To all? whom it may concern:

Be it known that I, FRANKLIN P. BATES, a citizen of the United States,residing at Indianapolis, in the county of Marion and State of Indiana,have invented new and useful Improvements in Wrenches, of which thefollowing is a specification.

My invention relates to new and useful improvements in wrenches; and itconsists in a peculiar form of construction of the same, and will behereinafter more fully described, and particularly pointed out in theclaims.

The object of my invention is to construct a simple and durable wrenchhaving the least possible number of loose parts or separate parts; and afurther object of this invention is to construct the main port-ion ofsaid wrench in one integral piece from a single piece of metal. I attainthese objects by means of the constructionpf wrench illustrated in theaccompanying drawings, in which similar numerals of reference designatelike parts throughout the several views.

Figure l is a side elevational view of a wrench embodying my inventionand showing the wood filling of the handle portion thereof in dottedlines for the purpose of more clearly illustrating the construction ofthe tang portion of said wrench. Fig. 2 is an edge or front view of thesame. Fig. 3 is a reduced side elevational view of the wrench, showingthe form of the tang portion thereof in full lines and also showing theform in which said tangis first forged; and Fig. 4 is a View showing thetraversing nut of the wrench.

The wrench is or may be of the usual wellknown type and is composed ofthe main member 1, having the fixed or permanent jaw 2, the handle ortang portion 3, and the sliding jaw 4, provided with the retaining-bands5 and 6, formed integral on said jaw 4 and which encircle therectangular portion of the main member 1 to guide said jaw 4 and topreserve its alinement with the fixed jaw 2 at all points throughout itsscope of adjustment. The jaw 2 is formed integral on the end of therectangular portion of the main member 1, and the opposite endof saidmemher is prolonged to form the handle-tang portion 3 and the screwportion 7, and the said jaw 2, main member 1, tang 3, and the screw7.are forged or otherwise formed in one in tegral straight or unbentpiece. The tang or handle portion 3 is preferably of a T-section, havingits flange 3 formed on the outer edge of the web 3, and the said web isreduced in depth at its center portion or bend 3 for the purpose ofreducing the area of resistance of the section at such point or bend andto facilitate the operation of bending said tang 3 at such point.

In order to practice my invention, I first construct the main portion 1,having the permanent jaw 2, the tang 3, which is at least double thelength of that of the usual handletang, the screw 7, and the head 8thereof, all of which elements are forged or otherwise formed, as bycasting, in one integral straight piece. I next form the threads on thescrewshank 7, and a screw-way 9 is drilled or otherwise formed in thehead 10 of the sliding jaw 4, and said way is made parallel with theface of the member 1 and of. a diameter sufficiently large to permit thefree entrance of the screw 7 when the end of the latter is broughtopposite to it. A transverse slit is nowcut or otherwise formed in thehead 10 at right angles with the center line of said screw-way and is ofa depth and width sufficiently large to permit the entrance of thescrew-nut 12, which latter is of a disk form and has its outer edgemilled in the usual manner. The nut 12 is drilled centrally and threadedto receive the screw-threads of the screw 7. I next apply the jaw 4 onthe member 1 with the face of the said jaw directed toward the face ofthe fixed or permanent jaw 2. I now bend the tang 3 upon itself till theend of the screw 7 enters the screw-way 9 of the sliding jaw 4. I nowplace the nut 12 in position in the nut-receiving slit formed in thehead 10 ready to receive the end of the screw 7 and still further bendthe tang 3 upon itself till fully bent into the desired form andtill thescrew-head 8 has entered the recess 13, formed in the edge or face ofthe member 1, at which time the screw -7 has fully entered the nut 12,which is continuously turned as the bending of the tang proceeds, andthe said recess 13 is provided for the purpose of receiving the endthrust of the jaw 4 through the screw 7, thereby releasing the tang ofall thrust and securing a rigid sliding jaw 4-, which is desirable.iVood fillings 14, dressed into the desired form, as shown in dottedlines in Fig. 2, are riveted or otherwise secured to the handle-tang ofthe wrench, and a band 15 surrounds the ends of said wood fillings andthe head end 8 of the screw 7, by which means the tang is reinforced andthe tang is made more rigid.

Having thus fully described this my invention, what I claim'as new anduseful, and desire to cover by Letters Patent of the United Statestherefor, is-

1. A wrench composed of a fixed jaw, tang and screw members, all formedin one single integral piece, and wherein the screw is formed on the endof the prolonged handletang, which tang is bent around upon itselfbringing said screw into position.

2. A wrench havinga main memherdivided into three integral elements andcomposed of a fixed jaw end, a screw end, and an intermediatehandle-tang member, and provided with a traversing jaw member, saidintermediate tang member being bent around upon itself to bring saidscrew member into position.

3. A wrench havinga main memberdivided into three elements, all forminga single integral piece, and composed of a jaw end, a screw end, and anintermediate handle-tang member, which latter member is graduallyreduced toward its central portion, substantially as and for the purposeset forth.

4. A wrench having a main member composed of a jaw end, a screw end, andan intermediate handle-tang member, said tang member having a T-formedsection and having the web of said T-section gradually reduced towardits central portion to a point intermediate between its ends,substantially as and for the purpose set forth.

5. The combination with a wrench composed of a main member having afixed end jaw, and a sliding jaw on said main member, of a tang portionformed integral on the end of said main member, and a screw formedintegral on the end of said tang portion, which tang portion, afterplacing said jaw in position on said main member, is bent around uponitself till the screw end thereof loosely enters the screw-way of thesliding jaw and till said screw is parallel with the line of the face ofsaid main member.

6. The combination with a wrench composed of a main member having arectangular portion, a fixed jaw formed integral thereon and ascrew-head-receiving recess formed in the face of the rectangularportion of said main member, and a sliding jaw loosely mounted on saidmain member, of a tang portion formed integral on the end of said mainmember, a screw-head and a screw formed integral on the end of said tangportion, said screw-head between said tang portion and said screw; andsaid tang portion, after placing said loose jaw in position on said mainmember, is bent around upon itself till the end of the screw thereofenters the screw-way of said sliding jaw and the screw-nut, and is stillfurther bent till the head of said screw enters and is lodged in thescrew-head-receiving notch and. till the said screw is parallel with theface of the main member, and means for securing said screw in properposition, substantially as and for the purpose set forth.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing witnesses.

FRANKLIN P. BATES.
